Arain barrel is full of water and used to water a garden. the rain barrel loses water at the rate of 2.5 gallons per minute. after seven minutes, the rain barrel contains 37.5 gallons. part a: how many gallons of water were initially in the rain barrel? show or explain your work. part b: write an equation in point-slope form to model the number of gallons (y) of water in the rain barrel after (x) minutes. show or explain your work. part c: if the rain barrel was full of water, how many minutes does it take for the rain barrel to drain so it contains 25 gallons of water? show or explain you work. part d: what is the total number of minutes it will take to completely empty the rain barrel? show or explain your work.

A. 55 gallons of water

B.

C. 12 miinutes

Step-by-step explanation:

The rain barrel loses water at the rate of 2.5 gallons per minute.

Part A. After seven minutes, the rain barrel contains 37.5 gallons. During those seven minutes, the barrel loses 2.5 gallons per minute, so it loses

gallons in 7 minutes.

Therefore, initially, there were

gallons of water.

Part B.

The slope is m = -2.5 (the barrel loses water, so the slope is negative).

Initially there were 55 gallons of water.

Hence, the equation in point-slope form to model the number of gallons (y) of water in the rain barrel after (x) minutes is

Part C.

To find the number of minutes it takes for the rain barrel to drain so it contains 25 gallons of water, substitute y = 25 and find x:

imma say 16%. sorry if its wrong. i'm doing the same stuff right now

step-by-step explanation:

“ a line segment that has the endpoints on the circle and passes through the midpoint is called the diameter. the diameter is twice the size of the radius. a line segment that has its endpoints on the circular border but does not pass through the midpoint is called a chord. a circle is the same as 360 small circle up the number 0 . i hope this .
